You can try disabling short selectors under Settings → Recorder Plugins → Windows. This will force OpenRPA to traverse the entire UI tree in the selector, and avoid it finding elements with overlapping names. If this is not enough (if you have multiple UI elements on the same “level” that are not unique), you can use the “hidden” selector property called indexinparent. You can read about it here and in other forum posts.
I’ll also recommend you watch this video that explains a little more about how selectors work in OpenRPA.
